Disabling "Add to Quick Access Toolbar" menu item

Hi Alexander,

You can temporarily set the CloneService.CanCloneToQuickAccessToolBar attached property to false to prevent a control from being cloned.

There is a RibbonCommands.AddToQuickAccessToolBar command in effect here. Ribbon has a CommandBinding to that command and the logic is as you saw, returns false if the control or a clone is on the QAT. Unfortunately there isn't a way to redefine that logic unless you alter the command binding to your own logic.

Thanks for your answer, it was very helpful for me.

I reached needed behavior by handling CanExecutePreview event of RibbonCommands.AddTooQuickAccessToolBar command.
It works fine:
When user calls ribbon button's context menu, CanExecutePreview event of AddToQuickAccessToolBar is raised. I handle it and, according to my internal logic, set CanExecute to false if needed. In this case "Add to Quick Access Toolbar" item of context menu will be shown disabled (grey) - all as I want.

But there is another question:
When I open QAT customization popup menu, it shows items from QuickAccessToolBarCommonItems collection like checkboxes. If some of this items is already in QAT, it will be shown as checked. If no - unchecked.
By handing CanExecutePreview of AddToQuickAccessToolBar I can only impact on enabled/disabled state of these checkboxes (will it be drawn greyed or not).
Is there any way how I can imact on logic, that determines is such checkbox item should be checked or not.

Thanks

Hi Alexander,

One of the criteria for matching items there is the attached RibbonControlService.Id property. So by changing that you could probably force an item unchecked. But there isn't a way to force it checked since we do additional checks to match ID and whether the item is a clone or not.

Thanks for your help!
